2 Claims. (Cl. 222-400.7)

Our invention relates to a combination involving a tank and liquid dispensing device, and more particularly to a tank for liquid and a means for dispensing the liquid within the tank, with ease and efliciency.

The object of our invention is to provide a tank for storing any type of liquid, such as chemicals, oils, water or the'like, and to equip the tank with a quick attachable and detachable dispensing means. 1

Another object is to provide a device of the character described, that may be manipulated without special tools or special mechanical skill.

Still another object is to provide a tank made of any material, or equippedwith a special lining to preserve the liquid stored therein, and constructing it in a manner to incorporate an adaptor and accessories to permit ease in transporting and dispensing.

A further object of our invention is to provide a combination of a tank and dispenser that efliciently dispenses the liquid contents of the tank with complete control, without danger of waste or spilling, and with a minimum amount of effort in its manipulation.

A still further object is to provide a sealing means for a connection between a dispenser and tank.

It is manifest to anyone familiar with the art, that chemicals, oils, or any other types of liquid, are stored and transported in tanks, or drums, constructed in a manner to enable them to be placed in any desirable and con venient location. It is also common practice to employ air pressure to dispense the liquid contents of the tank. However, quite frequently it requires considerable effort and mechanical skill to prepare the assembled unit for its function, and it is the prime object of our invention to provide a combination of a tank and dispenser, in which both units are arranged in a manner to be made adaptable to one another for their efficient performance.

The device is simple in construction, easy to manipulate, yet highly efficient for the purpose for which it is intended.

Other and further objects of our invention will become more apparent as the description proceeds, when taken in conjunction with the drawings, in which:

FIGURE 1 is a side view of the tank showing the adaptor for the dispensing unit extending upward from the top plate, and showing the capacity gauge on the vertical side and the channels or bottom rails to accommodate the fork of a conventional lift truck;

FIGURE 2 is a perspective view of the top of the tank as illustrated in FIGURE 1, and showing the adjustable clamp and screw arrangement to seal the adaptor, and

also showing the lateral re-inforcing rail for the top plate;

FIGURE 3 is a similar view'as shown in FIGURE 2, with a perspective view of the dispenser in engagement with the adaptor;

FIGURE 4 is a vertical cross-sectional view of the dispensing device, in its relation to the adaptor and illustrating the valve arrangement, taken at the line 4-4 in FIGURE 6;

FIGURE 5 is a vertical cross-sectional view of the dispenser, showing the clamping method employed to place it into engagement with the adaptor on the cover of the tank, taken at the line 55 in FIGURE 6; and

FIGURE 6 is a top view of the dispenser assembly.

Similar characters of reference indicate corresponding parts throughout the several views, and referring now to ice the same, the character 10 shows a storage tank which may be of any size, shape, or contour, made of any type of material, or coated on its inside with a protective coating, depending on the liquid stored therein. The tank 10 is shown equipped with a flange extending outward from its upper peripheral edge shown as 11, and a cover 12 is shown sealing the top of the tank 10, when used with a gasket 13 and a plurality of bolts or rivets 14. Obviously the tank may be sealed in any other efiicient manner.

The bottom of the tank 10 is shown in FIGURE 1, equipped with a pair of channels 15, to permit a fork from a lift truck to be inserted below the tank, and a conventional sump 16 is shown to provide a low point in the tank.

We also show a transparent capacity gauge 17 extending along the vertical wall of the tank 10. However any type of conventional gauge may be employed, to determine the amount of liquid in the container or tank.

The cover 12 is equipped with an adaptor 18 extending therethrough, which adaptor is equipped with a peripheral flange 19.

A liquid dispensing unit, generally shown as 21, is designed to seal the adaptor 18, after the cover 12 has been removed and to enable liquid to be removed from the tank 10.- The dispensing unit 21 consists of a sealing plate 23 of a shape or contour to fit the flange 19, and a gasket 24-is employed as a seal between the sealing plate 23 and the flange 19 when the liquid dispenser is applied.

The plate 23 is equipped with a flanged channel member 25, centrally attached thereto by means of bolts 26, or in any other convenient manner. The channel 25 has an opening 25a therein and a longitudinal slot 25b. A threaded member 27 extends through the slot 25b of the channel 25 and has a circular locating means 28 shown resting on a thrust bearing 29 disposed within the opening 25a within the channel 25.

The threaded member 27 threadedly engages a yoke member 30 and a pair of clamp members 31 are pivotally mounted to the yoke 30 at 32. The clamp members 31 are tong shaped at their lower end 33 for engagement with the bottom surface of the flange 19 at 34. The upper end of the threaded member 27 is equipped with means for revolving it such as a hand wheel 35, the hand wheel 35 being attached by means of the pin 36, or in any other convenient manner.

The plate 23 is also equipped with a pair of apertures, one to accommodate a longitudinal tube 37 extending downward through the tank 10 into the enclosure formed by the sump 16 at the bottom of the tank 10, and the upper end of the tube 37 is shown provided with an elbow 38, and a control valve 39 for dispensing the liquid. The other threaded aperture in the plate 23 is shown supporting a threaded nipple 40 extending upward therefrom and-shown equipped with a T 41 supporting a relief valve 42, which may be a pop-safety valve, and a tube 43 extends from the T 41, and supports an air-valve 44' and a tube 45 leading from the source of air pressure, such as a compressor or the like (not shown).

From the above description, it will become manifest thatthe operation of the entire unit is very simple and efficient. After removing the cap 22 from the adaptor 18, the entire assembled dispensing unit is applied. The tube 37 will extend into the liquid disposed within the tank 10, and by revolving the hand wheel 35, after the clamping arms 31 are placed below the flange 19 of the adaptor 18, the threaded member 27 will move the yoke 30 upward, thereby pushing the plate 23 downward against the sealing gasket 24 on the flange 19, creating an air tight seal when all the valves are closed.

By opening the valve 44, air from a compressor or the like (not shown) will be forced into the tank 10, and when the valve 39 is opened the contents of the tank will Patented June 2, 19 64 be forced outward and controlled by the valve 39. The valve 42 is employed to exhaust the air pressure, or if the valve 42 would be a safety valve, it will insure a proper air pressure in the tank 10, when the valve is set at a pre-determined pressure.

By manipulating the wheel 35 on the threaded member 27, the entire dispensing unit 21 may be removed, or placed into position.

To position the liquid dispensing unit 21 for the tank 10, the positioning means 28 is placed in the opening 25a of the channel 25. And the threaded member 27 projects through the longitudinal slot 251). To position the clamp members 31, the threaded member 27 is disposed along the longitudinal slot at a point substantially equidistant from where the clamp members 31 have the tong portions contacting the underside of the adaptors flange 19.

Although we have shown a specific construction of our device, we are fully cognizant of the fact that many changes in the shape and contour may be made without effecting its operativeness, and We reserve the rights to make such changes as we may deem convenient without departing from the spirit of our invention, or the scope of the claims.

We claim:

1. In combination: a tank having an adaptor extending therefrom; a liquid dispensing device detachably connected to said adaptor comprising plate means for sealing said adaptor by being pressed thereagainst, said plate means being equipped with means for pressurizing .,0
